Gene expression in the epidermis including guard cells of phot1 phot2 and pGC1::SOC1-GFP/phot1 phot2


ABSTRACT: Stomata pores are surrounded by a pair of guard cells in the epidermis in plants. Stomata apature is controlled by environmental factors. Stomata opening is also enhanced by introduction of SOC1-GFP driven by GC1 promoter in phot1 phot2 double mutants (pGC1::SOC1-GFP/ phot1 phot2). Epidermis including guard cells were isolated from phot1 phot2 and pGC1::SOC1-GFP/phot1 phot2 and gene expression were analyzed. phot1-5 phot2-1 in gl1 background (phot1 phot2) and pGC1::SOC1-GFP/phot1 phot2 were grown under 16 h light / 8h dark, constant 22˚C conditions for 4 to 5 weeks. Epidermis including guard cells were isolated from leaves of these plants. Three biological replicates were used.

Stomatal movements are regulated by multiple environmental signals. Recent investigations indicate that photoperiodic flowering components, such as CRY, GI, CO, FT and TSF, are expressed in guard cells and positively affect stomatal opening in Arabidopsis thaliana. Here we show that SOC1, which encodes a MADS box transcription factor and integrates multiple flowering signals, also exerts a positive effect on stomatal opening. FLC encodes a potent repressor of FT and SOC1, and FRI acts as an acti  ...[more]
